THERMODYNAMICAL EVALUATION OF A SCALE ICEMAKER WATER-AMMONIA ABSORPTION SYSTEM BASED ON EXPERIMENTAL DATA
|
| |
|
Summary :
|
|
ABSTRACT: ABSORPTION HEAT PUMPS HAVE RECEIVED GROWING ATTENTION IN THE PAST TWO DECADES. THE INCREASING COST OF ELECTRICITY HAS MADE THIS HEAT-POWERED CYCLE ATTRACTIVE FOR BOTH RESIDENTIAL AND INDUSTRIAL APPLICATIONS.
FURTHER DEVELOPMENT OF THIS TECHNOLOGY DEMANDS RELIABLE SYSTEM SIMULATIONS. SEVERAL COMPUTER MODELS HAVE BEEN DEVELOPED THAT HAVE PROVEN TO BE VERY VALUABLE TOOLS FOR DESIGN OPTIMIZATION. HOWEVER, MUST OF THEM DO NOT TAKE INTO ACCOUNT THE HEAT AND MASS TRANSFER CHARACTERISTICS.
THE OBJECTIVE OF THIS WORK IS TO CREATE A MATHEMATICAL MODEL COVERING THERMODYNAMICS, HEAT AND MASS TRANSFER AND FLUID MECHANICS PHENOMENA, INVOLVING BOTH CONSTRUCTIVE AND EXTERNAL PARAMETERS, IN ORDER TO SIMULATE NUMERICALLY THE STEADY STATE PERFORMANCE OF ONE ABSORPTION REFRIGERATION SYSTEM. THIS MODEL WAS VALIDATED AGAINST EXPERIMENTAL DATA WITH GOOD AGREEMENT.
KEY WORDS: ABSORPTION REFRIGERATION, ICE MAKING, MATHEMATICAL MODEL, SIMULATION.
